CHURN.

SPECIFICATION forming part of Letters Patent No. 410,888, dated September 10, 1889.

Application tiled May 29, 1889. Serial No. 3] 2,592. (No model.)

To all whom t may concern,.-

Be it known that I, FREDRICK l-I. HAMAN, a citizen of the United States, and a resident of Vapakoneta, in the county of Auglaize and State of Ohio, have invented certain new and useful Improvements in Ohurns; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, and to letters or Iigures of reference marked thereon, which form a part ot this speciiication.

Figure 1 of the drawings is a vertical transverse section. Fig. 2 is a plan view. Fig. 3 is a horizontal sectional view. Figs. 4. and 5 are det-ail views.

This invention relates to churns; and it consists in the construction and novel coinbination of parts, as hereinafter described, and pointed out in the claim.

In the accompanying drawings, the letter A designates the body of a barrel-churn suspended in suitable bearings on a trame B by hangers C and D.

E indicates an annular' ring for the reception of the churn-head, said ring having four shouldered hook-lugs H thereon, arranged at equidistant points, and under which project the ends of arins L through staples I of the churn-head K when the lid is in place. The arms L have at their inner ends hook-extensions b, projecting from shoulders a, in order that they may be clamped around the pivots Z of their bearings c on the spider N. The spider N, carrying the bearings c, is a metal casting having a central opening d,surrounded by a raised rim or shoulder e, to engage stop g on the edge of a cam-lever O, adapted to fasten the parts together. The cam-lever is eccentrically pivoted in the bifurcated or slotted upper end ot' a threaded rod P, Which passes through the openings d of the spider and is screwed into an internally-threaded casting R, bolted at 1l to the center of the churn-head. After the threaded rod P has been screwed into the casting R a sufficient distance the cani-lever O is depressed until the inner shoulder ot the angular stop g engages at any point against the raised rim or shoulder of the said casting. When the lid is placed on the churn and the end of the cam-lever O is depressed, the outer ends of the Jfour oblique arms L are projected under the shoulders D of the hook-lugs H by the pressure ot the cam on the spider, and the lid 'or cover' is locked iirmly in place.

It will be observed that the head of the calnlever is pivoted diagonally opposite the stop g in order that after the said cam passes the center the said stop shall prevent its further passage and retain it in position at any point around the raised rim of the central opening of the spider.

The hangers C and D of the churn each consist of a casting having centrally-perforated base A', provided on its inner surface with projections or spurs c', and a hollow journal d', projecting from the base. The hangers are secured to the side of the churn on opposite sides by bolts e', passing through the middle portions of the staves and through the hollow journal, the said bolt being held in place by a nut g on its outer end. The spurs c of the base engage the i'ace of the outer surface of the staves and serve to hold the hangers firm when bolted in position. One of the hangers D is extended outward and usually tapering toward its end to receive a handle or crank S, which is secured with the hangers to the side of the churn by a bolt and nut in a manner similar to that described in connection with the hanger C of the opposite side. The tapering end of the hanger Or journal C is flat-tened on one side at 7L to engage a corresponding iiat surface k in the opening Z of the crank to prevent the latter from turning on its bearing.

The body of the churn A is constructed of staves joined together at their meeting edges by V-shaped tongues t, rising from radial shoulders t,.adapted to tit in corresponding V-shaped grooves f of the adjoining stave, having radially-beveled edges t" on each side of the groove to engage the inwardly-inclined shoulders of the tongue t.

The obj ect of the construction is to provide in each stave a continuously.-penetrating tongue to engage the corresponding groove in the adjoining stave, acting when the surrounding hoops are being driven over the barrel to bring the staves neatly together, and serving to form a closer joint than can be ob- IOO tained hy the ordinary rectangular tongue und groove.

The l'rfnne in which the ehurn is hung eonsists of the opposite vertienl uprights A, secured at their lower ends hy u tenen-andauertise joint to the hase-pieces B, respectively, the upper ends of the uprights furnishing hearings for the hangers of the ehurn. rThe inortises are supplied with glue, in which the tenons are sunk. The sides of the frame are niortised half-way through their thickness at 71, to reeeive the shouldered ends of the eenneeting-ronnds 7.". The ends of the rounds are also sunk in glue, sind, being prevent-ed from passing through the sides hy their shoulders, the fuee walls of the mortises preserve the frznne :it these points from Contact with water or moisture, which would otherwise render the joints defective. The sides of the frame are further strengthened by holt-rods of xnetal'l, passing tl'rrough from side to side :tt the buse of the 'frame and parallel und udjeeent to the rounds of the freine.

llnving described this invention, what I elariin, and desire to seeure by Letters Patent, is

In u revolving ehurn,the combination,with the stave and the hollow-journal enstinghnving a base itting the outer surface of the stave and provided with inner spurs te engage said stave, of the bolt extending ont- Wurdly through the steve und journal-ensting and provided with :t nut in its outer end, substantially as speeiied.

In testimony whereof I allx inysignuture in presence of two Witnesses.
